Got mine in Feerrott from Xiucozcatl the Feared. Second Scuffed container I've gotten in Feerrott in the last 45 days. From reading other posts the scuffed containers appear to be random drops from any named in the HoT expansion. I've camped Xiucozcatl and killed over 20-30 times since the HoT expansion, this is the first and only time I've seen the Scuffed Traveler's Rucksack or any other Scuffed item drop. Maybe drop frequency has been increased recently....
